Abstract

Parameters characterizing the atmospheric turbulence in a 16km maritime optical link were measured for the months of January through June of 2007 on a continuous basis, as conditions allowed. Both the scintillation index σI2 and the atmospheric structure constant Cn2 are found to have a strong dependence on the air-minus-water temperature difference. There is no obvious diurnal variation of Cn2 or of σI2 akin to the reduction in turbulence level seen in terrestrial links in the hour before sunrise and the hour after sunset. Results from the analysis of these data highlight a need for new approaches to modeling beam propagation in a maritime environment.
